I can understand your concern.
what are the provisional diagnoses in your mind please mention that also. and what are you trying to prove and what cause are you trying to rule out would like to know that also.
are you inclined on these two tests only or any other tests can be suggested to you?

you should consult a doctor rather than playing a DOCTOR on yourself. it can be harmful.
if you do not know anything related to medicine, you should avoid taking such things in your hands.
